Hi folks:
I was on the verge of putting my 80 Series landcruiser into the Auto Electrician to have a new wire loom fitted to fix the voltage drop problem with my truck, prior to installing some halogen headlights (currently have sealed beams). On reading through the threads here I am now aware of the "blue" Xenon lights which require less power. My question is, if I was to take this Xenon option, should I still upgrade my wiring loom for voltage drop, or will it not matter too much with these globes?
Many thanks

By reports here, those Xenons are the go. I'd still put the heavy loom in, on off chance you may want to use heavier globes in high beam later. We have Piranha loom, and 100 watt h/beam. Also easier on the dip switch circuit, which are REAL expensive to replace.

Because the xenon are standard wattage, they should be right with std setup. Don't have the high heat output of heavier globes either. Hooroo...

Are you buying new headlights to fit globes? You can get them for next to nothing in local paper/wreckers.The same lights are fitted to some old Sigma models also datsun and others.The lamps are steel and you can fit 90/100 watt globes no problems.I have also used the +50 55/60 watt xenon globes ,not bad with standard wiring .The blue globes are crap , my opinion I had them two weeks not any better than the others and take a lot of getting used to , the road looks weired.

HI Ray:
The plan was to buy new headlights, but I think your suggestions is definitely worth a look. I have created enough millionaires in the spare parts trade already. Your comments on the blue globes are also something I will take on board. I can try them and dump them if they don't work safisfactorily. Much appreciated.

I know this a popular mod on the 80 series but when i checked the voltage on my headlight the voltage was 11.8 v and the battery voltage was 12.1v. (very accurate meter)

So the voltage drop is only 0.3 volts, Personaly i think that small a v/drop wouldnt make any difference but others say the wiring upgrade works.

Does 0.3 volts make any difference ?

H/duty loom protects high/low beam switch from destruction, especially with high wattage globes. Found out on HJ60 we had some years ago, about $400 for replacement loom.

Even at 13.8V, the voltage drop in your 80 is still less than 0.4V, or else my maths is crap.

I tried those blue globes once, from Autobarn, one blew 10 mins after fitting it. Didn't mind the colour, while it lasted! Hooroo...

As 40% of my driving is in darkness nothing beats good lighting, I have an upgraded loom with 100/130 globes, low beam is still very short but well lit hig beam is very pleasent, blow on av 1 / 6 months, to me worth the little inconvenience.

Yes- the "Blue" globes they sell in Supercheap are crap- bought some and one blew in 1 week, the second in about 3. Light was NObetter than standard.
Now have 130/90 H4 globes with better wiring and its beaut!
Don't know about the "genuine" xenon globes.

i have the xenon globes on my patrol have standard loom and have done many thousand ks of night driving, the blue light took a bit of gettig used to but now swear by them, found them to be very effective in rain and fog could stay on high beam with no reflection was really impressed with that. I also run rally 4000,s which are fantastic as well . Col
